spright review
An open-source command-line tool for packing sprites and generating game-engine metadata.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
For developers preparing sprite assets for games, spright is an open-source command-line tool that packs images into one or more sprite sheets and generates accompanying descriptions. It accepts images and sprite definitions from files or sequences, and can detect sprite regions to help complete those definitions. Users can assign IDs, set pivots, and group sprites with tags such as animation names. Its self-hosted approach suits solo developers and small teams comfortable configuring a command-line workflow; it is less suited to people seeking a visual editor or a managed service.
Packing and annotation are the product’s central strengths. Available modes include binpack, compact, rows, columns, single, and layers, with configurable size constraints. Sprites can be trimmed to non-transparent regions using rectangular or convex trimming, and can be rotated clockwise by 90 degrees to improve packing efficiency. The tool can produce multiple sheets and image files in PNG, GIF, TGA, or BMP formats. Output descriptions are generated from templates, which can carry sprite metadata into a game-engine workflow; example templates include Phaser. This combination makes spright more configurable than a tool focused only on arranging images, though it expects users to work with definitions and templates.
The project is distributed under the GNU GPLv3 and has a free, open-source model. Visual Studio Code is the listed integration, and documentation is the listed support channel. That makes it a reasonable fit when source-available tooling and direct control over packing output matter more than broad integrations or dedicated support. Choose spright for configurable packing, trimming, animation grouping, and template-based metadata in a self-hosted workflow. Consider an alternative if your team needs a graphical interface or support beyond documentation.
spright pros and cons

- Groups animation sprites and generates metadata from templates.
- Where it doesn't
- Uses a command-line, self-hosted workflow rather than a graphical editor.
- Integrates with Visual Studio Code; no broader integrations are specified.
- Documentation is the listed support channel.
